Power supply module for fire protection systems EN54M 27.6V/10A/2×40-65Ah EN54M-10A40-65

Power supply module for fire protection systems – reliable power and protection

This power supply module, designed for fire alarm systems, provides uninterrupted power to critical devices. Designed in accordance with EN54-4 standard, it guarantees high reliability and safety of operation. It will be suitable for both new and modernized facilities requiring certified fire protection. The module is compatible with batteries with a capacity of 40 to 65 Ah, providing flexibility in component selection.

Construction and functionality

The power supply is characterized by a compact design (237 x 168 x 55 mm) allowing installation in fire protection system enclosures or on a DIN rail (using an optional EN54M-DIN1 bracket). It has two independently protected AUX1 and AUX2 outputs with a voltage of 27.6 V DC, allowing to power various system elements. Built-in protections (SCP, OLP, OVP, UVP) protect against short circuits, overloads, overvoltages and undervoltages. Additionally, it has an EXTi input for connecting external alarm signals. The battery charging current is 2.6A.

Safety and compliance with standards

The module meets the requirements of EN54-4 and EN12101-10 standards, confirming its suitability for professional fire protection systems. It has a CNBOP-PIB certificate of conformity no. 1438-CPR-0630. Built-in diagnostic functions monitor the condition of the batteries (voltage, resistance) and signal AC network failures and general system problems using EPS and ALARM relay outputs. The device is equipped with reverse polarity protection and battery circuit continuity monitoring. The manufacturer's warranty is 3 years from the date of production.
